Hi,
i have an video with an cocktail-glass and black background.
look here:




do you know an easy way to make this transparent?
or
do you know an tutorial i can watch with any good tipps for this work?

it dont need to be exactly... a little black border on the side of the glass is no problem...
the video is for an interface. i cut one image out and put it on the interface here (just for a preview or example):



sorry for my bad english.. its not my first language. hope you understand and can help.

thanks a lot

Hi
Other than testing different blending modes. I would apply "Unmult" a free useful plugin for getting alpha channel from black...
- see the video. Again it's a free plugin by Red Giant.
Good luck

Thanks for your help. Knoll Unmult doesnt work with After Effects 2018.
But i found a free plugin that worked: http://www.videocopilot.net/tutorials/color_vibrance_plug-in/

Rotobrush might work.
